Newest Ballast Design Addresses Expected European Automotive
'Daylight Headlight' Regulations Fairchild Semiconductor's (NYSE:
FCS) Global Power Resource(TM) Design Center in Germany recently
completed designs enabling automobile manufacturers to meet the
proposed European daytime headlight (daytime running light) safety
regulations with a new ballast design utilizing SEPIC topology.
This new design is ideal for low voltage DC/DC applications, such
as automobile headlights. Fairchild's ballast designs offer a wide
range of options, including optimizing factors such as EMI and
efficiency, and are highly variable in terms of input and output
voltage as well as output power. "Fairchild's Global Power Resource
design center in Europe also developed a design, using the SEPIC
topology, to drive up to seven LEDs with 30V max output and 350mA
constant current as well as up to 36 low power LEDs with 120V max
output with 70mA constant current output," said Ole-Peter Brusdal,
regional vice president, European Sales and Marketing. The use of
car headlights during the daytime is expected to become mandatory
in the European Union under plans being discussed by the European
Commission to cut the number of road accidents. Today's automobiles
increasingly use high brightness LEDs of up to 1W of power. However
daytime headlights typically require five to seven LEDs to comply
with the expected new standard. Ideally, these LEDs should be
connected in a series to ensure identical current and therefore the
brightness of each device. SEPIC topology can transform voltages up
as well as down, easily meeting these requirements. While SEPIC
topology is ideal for DC/DC applications, it is also an excellent
choice in non-isolated low power AC/DC applications, such as power
supplies for industrial controls and white goods. This topology
offers cost effective solutions, achieving an efficiency of about
80%. "Fairchild is fortunate to have the caliber of talent in Dr.
Michael Weirich and his team to develop innovative designs using
SEPIC topology in a expansive range of low voltage applications,
such as daytime running headlights, DC/DC converters and off-line
AC/DC solutions," continued Brusdal. The Global Power Resource
center in Fuerstenfeldbruck, is resourced with expertise and
equipment targeted to provide comprehensive power design solutions
for electronic applications in the principal European end markets -
industrial, consumer and automotive. With significant power design
experience, the design and application lab is staffed by highly
qualified systems, applications and component engineers. Able to
turn around designs in as little as two weeks, the center provides
customers with fully engineered solutions, including evaluation
boards; detailed reports including information for
'Bill-of-Materials' (BOMs) and turnkey designs, including CAD files
that can be incorporated into customers' designs; and application
notes. It is one of seven such centers operated worldwide by
Fairchild, The Power Franchise(R), to develop complete system power
solutions in the computing, communications, consumer, industrial,
automotive and display segments. Fairchild plans to nearly double
the number of design labs this year, with the addition of six new
facilities located in South America, China and Korea. About
